SHOE HEEL.

Application med my 25, 1925. sei-iai No. 32,792.

This invention relates toV a. shoe heel and one object of the inventionis to provide improved means to securelyrhold a lower heel lift whichwill preferably be formed of rubber upon a shoe heel and to permit otthis rubber heel being removed land a new one easily and quickly put inplace.

Another object of the invention is to provide improved sockets which areso constructed that they may be inserted downwardly through openingsformed in a litt above the rubber ground-engaging litt and be heldagainst rotation inthe openings in which they fit. This aermits theheel-securlly screwed into or out of place without the sockets turningwith the screws.

This invention is illustrated in the accompanying drawing, whereinFigure 1 is a view looking at thev under fac-e o'f the heel littagainstwhich the rubber heel or lift is secured;

Fig. 2 is a longitudinal vertical sectional view through a portion of ashoe with the improved heel in place;

Fig. 3 is a perspective view of one of the sockets shown in use in Figs.1 and 2;

Fig. 4 is a perspective view of a modified form of socket.

The heel which has been shown in Fig. 2 is provided with an upper lift 1which is an ordinary leather lift and is secured to the heel portion oitthe shoe sole 2 by nails 3 which are driven upwardly through the litt 1and shoe sole 2 and clinched at their upper` ends. The portion of theheel which forms the subject-matter of this invention includes a lift 4which may be formed o leather or any other suitable material and a lowerlift 5. The lift 5 will, in the preferred form, be made of rubber but itmay be a leather litt it so desired. The litt 4 has openings 6 formed init which will be preferably spaced from each other about the lift, asshown in Fig. 1. The openings 6 are non-circular when viewed in crosssection and may be elliptical, as sho-wn in Fig. 1. Attheir upper endsthe openings 6 are enlarged by counterboring from the upper tace of thelift so as to provide seats 7 which will preferably be circula-r whenviewed :trom the upper face of the litt. The lower lift 5 is alsoprovided with openings which are indicated by the numeral 8 and extendupwardly from the lower or Vground-engaging face of the lift and havetheir upper endportions of a re- 6 so that the openings 8 are disposedin axial y alinement to the openings The lower groundengagmg litt 5 isto be securely but releasably fastened to the liftV 4 and in order to doso there has been provided sockets 10 which are Inserted in the openings6 of the litt 4 and securing screws. 11 which are passed upwardlythrough the openings 8. The sockets 10 will conform in cross section tothe contours vol the openings 6 and, therefore, when the openings areformed, as shown in Fig. 1, the sockets will each be elliptical in crosssection, as shown in Fig. 3. At its upper` end each socket car# ries acircular head or liange 12 which is'oi a diameter and thickness to fitsnugly in a seat 7 with its upper face lflush with the upper face of thelitt. The fact that the socket is non-circular in cross section and titsinto a correspondingly shaped opening will prevent it from rotating butin order to permit the socket to be very securely held in place openings13 have been formed in the flange 12 so that nails 14 which are drivenupwardly through the lifts 4 and 1 and sole 2 may pass through theopenings 18. A threaded bore 15 extends axially through the socket andwill preferably be of a diameter corresponding to the diameter of theupper end of the opening S-with which it registers. By having thesockets inserted downwardly through the openings 6, their flanges 12will be disposed at their upper.

ends and when the litt is placed against the under face of the lift 1and the securing nails 16 driven into place the sockets will beprevented rom having any movement which might tend to loosen them in theopenings. The nails 16pass through the lit'ts 4 andD 1 and shoe sole 2and are clinched at their upper ends, as shown in Fig. 2. It will,therefore, be seen that when these nails are put in place the lift 4will be very securely held. After the lift 4 has been put in place andsecured, the litt 5 is placed against the under face of the lift 4 andthe screws 11 are inserted through the openings 8 and screwed into thethreaded bores ot the sockets. These screws have heads 17 of a size tofit snugly in the enlarged portions of the openings 8 and the screwspass through metal washers which may be disposed about the Shanks ofthey screws und between the heads 17 and should rs 9 ot the openings, asshownat the left in Fig. :2, or may be embedded in the lift and have adiameter greater than the openings; S, as shown at the right .inithislligure. t willr` therefore, be seen thnt the screws muy be tightenedwithout theh'ft bel ing worn et the shoulders and that there will beless danger of the screws being;l dragged"A n exemple ot which is shownin Fig. Re

rung to Fig. d, it will be seen' that the socket which indicated bythe'numeriii l' is to eome extent substentinlly eireuliir 'in eroseseetion or end elevation' but at oppoeite pointe is provided withtapered Side extensions or ribs Q0 which extend rndinlh' of the soo A:etfrom the head 21 to the' 'ree end et the soo/liet. By making nee' ofthis forni ot socket, the openings in the lift Lt een very easily mede bv siinpl57 drilling eireuinr'open'- inge in the litt and then iilling'or cutting eide notches4 ot the proper depth to receive the ribs 20. l

There hns, therefore, been provided Shoe heel includingupper and lowerlifts it and 5 w iieh may be easily und quickly :tpplied2 to n shoe orboot heel either et the time; oi making the shoe or boot or later after:t cer`- tain number of lifts usunlly provided have been removed.i/Vhen` the lower ground-engnging litt is worn out7 it is simplynecessary to remove the screws and but n new lift in piece.

Having thus described the invention, I claim:
